COATING COMPOSITION FOR SURFACE TEMPERATURE REDUCTION
20200216680 · 2020-07-09 ·

The present technology provides a coating composition suitable for maintaining a cooler surface temperature in the presence of a UV source, e.g., the sun, as compared with a conventional coating composition. The present coating composition can reflect the sun's rays to provide a cooler surface when compared to other compositions of similar colors. The coating can be used to coat a variety of substrates and can be used, for example, as a coating for walking surfaces. When applied to a walking surface, the coating composition may provide a cooler surface that is barefoot-friendly, even in the presence of the sun or other strong UV source.
